The T10 Turbidimeter is programmed with two internal calibration options:
•Guided Calibration
•Free Calibration
A full guided calibration of the T10 is recommended once every 3 months at a minimum, to compensate for
changes in light bulb intensity. This calibration is not to be confused with the ‘software calibration’ performed
through PC-Titrate when using the Automated Turbidity setup. This calibration is accessed by navigating
through the T10 meter menus and is only applied internally to the meter.
The Free Calibration can be used to fine tune the measurements by adjusting the internal calibration curve to
match a single point. You also have the option to perform a Free Calibration on multiple points, but this is only
recommended when using the T10 in the Benchtop or Portable setup. When using the Automated setup, the
Free Calibration is only recommended for ‘Zeroing’ the instrument.
The Guided Calibration option is to be performed with cuvette inserts provided with the meter, or in a separate
kit. It is imperative that the proper cuvettes are used for the calibration, and that the proper standards are
used. The standards for the guided calibration are listed below:
1. 0.02 NTU
2. 20 NTU
3. 100 NTU
4. 800 NTU
To perform the Guided Calibration, follow the procedure below:
1. Ensure the T10 turbidity meter is turned on. If calibrating on an Automated T10 system, empty the
turbidity line of storage water, and remove the flow cell. Refer to Technical Bulletin 2020-008 for
instructions on removing the flow cell from an Automated T10 Turbidity meter.

2. Wear Gloves *IMPORTANT* and retrieve the T10 Sealed Standard Calibration Kit.
3. Hold the MENU button for 3 seconds, until you see ‘Menu’ appear on screen.
4. Press the DOWN button to show ‘Calibrate’ on screen, then press READ. You will see ‘Guided Cal.’ on
screen, press READ again to start the calibration.

5. Using a lint-free wipe, wipe down the sides of the sealed 0.02 NTU standard cuvette, then place it in
the measuring chamber with the alignment mark facing toward the user and close the lid. Press READ
to start the measurement.
6. You will see ‘Reading Standard’ appear on screen as the meter takes the 0.02 NTU reading. At this time,
gently invert the 20 NTU standard 10 times, and also wipe the sides of the cuvette down with the lint-
free wipe.

7. When the screen prompts you to insert the 20 NTU standard, remove the 0.02 NTU standard cuvette
and place it back in the carry case, then insert the 20 NTU standard into the measuring chamber and
close the lid. Press READ to start the measurement.
8. Repeat steps 6 and 7 for the 100 NTU and 800 NTU standards. NOTE a passing calibration will not show
any notification after reading the 800 NTU standard and will simply return to the calibration menu. If
the calibration is determined to be out of spec (slope between expected NTU and recorded NTU is
<0.25 or >4.0), a message will appear saying ‘Calibration Fail – Check the Blank and Standards’.
9. Press the ESC button until the NTU reading appears back on screen.
NOTE 1: At any point, the user can hold the ESC key for 3 seconds to abort the guided calibration.
NOTE 2: Do NOT store standards in high temperature, or in direct sunlight.
NOTE 3: If two standard readings are too similar, it will display Same Standard? and wait for re-read.

The T10 turbidity meter Free Calibration is a quick, 1-point adjustment to the T10 meter’s internal calibration
curve. For end-users operating a Manual T10 Turbidity meter, the Free Calibration is performed with one of the
screw-cap cuvettes, filled with the desired standard for free calibration. MANTECH recommends performing the
free calibration with an NTU standard around the mid-point for expected sample results. Multiple free
calibrations can also be performed, in succession.
The Free Calibration is to be used mainly for ‘Zeroing’ the instrument with the MANTECH flow-cell, when using
the Automated Turbidity setup.
To perform the Free Calibration, follow the procedure below:
1. Ensure the Turbidity Meter is turned on.
2. Wear Gloves *IMPORTANT* and retrieve a T10 Turbidity screw cap cuvette.
3. Prepare a Turbidity standard that is around the mid-point of expected sample results. Use the dilution
chart below for preparing 40mL of various NTU standards from 100NTU stock solution:
NTU Standard
mL 100NTU Stock
mL DI Water
NTU Standard
mL 100NTU Stock
mL DI Water
0.5 NTU
0.2 mL
39.8 mL
10.0 NTU
4.0 mL
36.0 mL
1.0 NTU
0.4 mL
39.6 mL
20.0 NTU
8.0 mL
32.0 mL
5.0 NTU
2.0 mL
38.0 mL
50.0 NTU
20.0 mL
20.0 mL

4. Hold the MENU button for 3 seconds, until you see ‘Menu’ appear on screen.
5. Press the DOWN button to show ‘Calibrate’ on screen, then press READ. You will see ‘Guided Cal.’ on
screen. Press the down arrow to show ‘Free Cal.’ on screen instead. Press READ again to start the free
calibration.
6. Using a lint-free wipe and DI water, clean and thoroughly wipe down the screw cap cuvette. Hold it up
to a light to ensure there are no smudges or residues on the glass before proceeding.
7. Without shaking the solution, ensure the prepared standard is well-mixed, then pour the standard into
the glass cuvette, filling to the point where the glass starts narrowing. Screw the cap tightly onto the
cuvette.
8. Once more ensure there are no smudges or residue on the cuvette, then insert into the T10 meter with
the alignment mark on the cuvette facing towards the keypad. Close the measuring chamber lid.

9. Press the READ button and the meter will start the measurement of the standard. You will see the
measurement result appear on-screen once done.
10. Use the arrow buttons to adjust the measured NTU to the expected NTU value of the standard. Hold
the SAVE button for 3 seconds to save the free calibration point.
11. Repeat steps 6-10 for additional standards, if desired. Once finished, press the ESC button until the
NTU reading appears back on screen.
12. Perform readbacks of standards to confirm legitimacy of the adjustment.
NOTE 1: If you find readbacks of low-end standards are inconsistent for Automated Turbidity, you may need to
perform a cleaning procedure on the flow cell. There is typically an automated rinsing schedule in place for
Automated Turbidity.
NOTE 2: If the above is not successful in cleaning the cell, the next step would be to remove the cell from the
unit and clean manually with IPA, DI Water, and Lint-free wipes. Refer to the ‘Turbidity Operation Manual’ for
more specific information on cell cleaning.

Push the READ key to power on the unit. The
display will show the instrument version, data
log, and date/time. If the meter does not turn
on, ensure that the USB cable is properly
connected to the port, and either a computer
or electrical outlet adapter. If using the
Portable version, check that the batteries are
oriented the correct way.
If the meter loses power at any point, it MUST
be powered on again manually via the READ
key. It will not turn back on automatically.
To power off the meter, hold the ESC key for 3 seconds until you see OFF appear on the screen. Note that the
Auto-Shutoff feature can be used to turn off the meter after a period of inactivity.
Sample analysis with the Benchtop or Portable T10 is performed using cuvette inserts in a similar manner to the
Guided Calibration. The T10 meter is able to store up to 1000 data points internally, each with an associated
Sample ID and User. To perform sample analysis, follow these steps:
1. Ensure the meter has a valid calibration by performing readbacks of the sealed calibration standards. If
the standards read back outside the acceptable range, it is recommended to recalibrate using the
Guided Calibration procedure before attempting sample analysis.
2. Prepare your samples for transfer to the glass cuvette vessels. It is important to use a transfer vessel
that is easy to pour out of, to avoid spilling sample on the outside of the glassware.
3. Put on laboratory powder-free gloves.
4. Ensure your cuvette glass vessels are as clean as possible before proceeding. If there is dirt, residue, or
smudges present, use a lint-free wipe to remove them from the cuvette.
5. Use your sample transfer vessel to pour sample into the glass cuvette, filling to the point just below the
cuvette neck where the diameter of the cuvette gets smaller. Screw the cuvette cap on to seal.
6. Wipe down the outside of the cuvette with a lint-free wipe once more.
7. Insert the cuvette into the measurement chamber, then press the READ key. The meter will turn the
lamp on and begin measuring. The measurement will display on the meter screen after a few seconds.
8. To save the measurement, hold the SAVE key for 3 seconds.
9. See pictures of this operation on the next page.
NOTE: The meter can be configured to prompt for a Sample ID to be entered with each sample, with every
saved result, or not at all. See Section 6 for information on configuring Sample ID entry.

Automated Turbidity operation with the Flow-Through Cell
requires valid module and software calibrations performed
within the last 90, and 30 days respectively. Refer to Sections
3.3 and 3.4 for instructions on performing these calibrations.
With valid calibrations performed, pour the samples into
sequential cups/tubes on the Autosampler tray, then use
one of the Autorun buttons on the bottom of the PC-Titrate
home screen to bring up a pre-made Timetable template, or
navigate through the drop-down menu Titrator>Run
Titration… to create a custom Timetable (see below).
When creating a custom timetable, there are 4
fields that must be filled out for each sample. The
“Schedule” field should have a schedule with
Turbidity operation selected. This may include
schedules with multiple parameters including
Turbidity. To select a schedule, double click on the
Timetable grid box under the “Schedule” header
and select a schedule from the pop-up window.
The “Order Number” field contains an
alphanumeric code used to link together all
samples in one run. If “Auto-Generate Order Number” is used, the following date code will be generated:
YYYYMMDD-N with “N” containing a number referencing the sequential runs through each day. The “Sample
Name” field contains a user-entered Sample ID unique to each sample. Names for multiple sequential samples
can be auto-numbered by right-clicking and dragging the sample name from the first sample’s grid box down to
the last sample’s grid box. The “Vial” field contains the numbered location of each sample on the Autosampler
tray. These numbers can be
auto-generated sequentially
by dragging from the first
sample’s grid box to the last
sample’s grid box. The
“Weight” and “Volume”
fields are not used for
turbidity operation. The
sample run can be set to start
at a later date/time by
entering values in the “Start
Date” and “Start Time” fields
for the first sample. Click the
START button to begin the
sample run.
